Install ClamAV on CentOS 6

Step 1. First add yum repository your system.

The EPEL repo is enabled by simply installing an RPM. Please use the command below to install the EPEL repository on your CentOS server.

#CentOS 6 – 32-bit

rpm -Uvh http://mirror.overthewire.com.au/pub/epel/6/i386/epel-release-6-8.noarch.rpm

#CentOS 6 – 64-bit

rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

Step 2. Install required ClamAV packages.

yum install clamav clamd

Step 3. Start the clamd service on system boot.

chkconfig clamd on
service clamd start

Update ClamAV’s signatures:

freshclam

Step 4. Configuring daily scan.

In this example, I will configure a cronjob to scan the /home/ directory every day:

nano /etc/cron.daily/clamav_scan

Add following piece of code into clamav_scan file.

#!/bin/bash
SCAN_DIR="/home"
LOG_FILE="/var/log/clamav/manual_clamscan.log"
/usr/bin/clamscan -i -r $SCAN_DIR >> $LOG_FILE

Give our cron script executable permissions:

chmod +x /etc/cron.daily/clamav_scan

Congratulation’s! You have successfully installed ClamAV. Thanks for using this tutorial for installing ClamAV in CentOS 6 system.
